    There is a pressing need to understand the impact of emerging contaminants on Arctic ecosystems; however, most standard toxicity tests are for temperate species. The lack of Arctic-specific tests may result in an underestimation of harm to Arctic organisms and contribut...

    Double-delay and short open calibration (SOC) deembedding are both useful for deembedding the results of a gap voltage source excited electromagnetic analysis. Previously, each approach has been viewed as distinct, each with its own advantages and disadvantages. This pa...

    In this paper, a new reconfigurable microstrip structure is presented where line impedance can be actively controlled to induce phase shift on a transmission-line signal. Micromachining is used to fabricate thin-film copper membranes in the ground plane below the transm...

    In a distributed multihop mesh/relay network (e.g., wireless ad hoc/sensor network, cellular multihop network), each node acts as a relay node to forward data packets from other nodes. These nodes are often energy-limited and also have limited buffer space. Therefore, e...
